如上图，返回的数据被加密处理，我们的目标是实现明文数据输出

查找关键词encrypt，定位到app.js源文件中，有6处匹配，可以分为如下两种形式

  1. 虽然包含了decrypt，看似是在解密，但是处于一个三元判断中，且函数后跟着一个.img_url，很明显不是在真正解密加密的返回数据

image-20221225202139883.png

  1. 处于一个函数内，并且将函数返回结果赋给了同一个字典变量下的另一个字段，基本确定其为解密函数

image-20221225202351590.png

打断点，刷新后单步进入函数

image-20221225202537376.png

此函数中o()是关键，JSON.parse的作用是将返回的结果转换为json格式，再次进入o函数

可以看到很长且复杂的解密函数，不用管直接复制下来，关键去找传入的参数和其中的外部函数即可

由s()知，传入的e="5e5062e82f15fe4ca9d24bc5"，i=0，n=0，a="012345677890123"，o=1，除了t其余均为固定值，只需确定a.a.decode(e)，方法为鼠标移动到a.a.decode，点击浮现的窗口中的FunctionLocation后的地址进行跳转
